I've been having Tokicos for a long time. And I love them. The blues = sux, but Illuminas is wonderful. I had GC + Illuminas for like 1.5 yr then swaped to Full Tokico Coilover where the shocks is the same as Illuminas, may be a little bit better since it's mad for full coilover. It's been almost a yr now and they do wonderfully well.
The reason I swapped was because the mech who first install my GC + Tok combo screwed up.
